OPEN-WORK ELAsTlo BRAID.

SPECIFICATION forming part of LettershPatent No. 362,440, dated May 3, 1887.

Application filed November 30,1886. Serial No. 220,299. (Specimens.)

To all whom 'it' may concern/.-

Be it known that I, BURKARD GOODMAN, ofthe city, county, and State of New York,

have invented a new and useful Improvement it has been generally the practice to weave such fabrics upon a loom, and prod ucethereby a close, compact, and substantially impervious fabric.

My invention consists in an opcn-workbraid having the characteristics hereinafter pointedv out and having elastic-cord threads introduced therein longitudinally, as hereinafter specified, making, as a result, a fabricwhich at all times is provided with openings or apertures allowing the free circulation of air, and which at the same time is substantially as elastic as the rubber cords. By reason of the loose braiding of the binding or filling threads they permit of the ready extension of the elastic cords. In

necessary to put the elastic cords under tension and do the braiding upon them while in that condition. Vhen these cords contract on the completion of the operation, the braid is still an open braid, analogous in some respects to open-work trimming-braids. The improved elastic open work braid differs from said old open-work braid not only inthe substitution of `elastic warp-threads for the non-elastic threads, but in the manner hereinafter indicated, in which the binding or lling threadsare interlocked or interlaced between the elastic warp-threads in contradistinctiou to being simply crossed by each other.

In my improved braid the braiding-threads are actually interlocked or braided between the adjacent longitudinal cords or threads, while in the old open-'work braid the braidingthreads simply overlie one another between the longitudinal threads 0r cords, without being actually interlocked or braided together at such points.

The advantages of this braid for many purposes, especially the making of such articles as Suspenders and garters, are obvious. The

material, while equally or more elastic than the present suspender-webbing, at the same time requires less `binding or non-elastic material for an elastic fabric of the same'width and thickness. It is obvious, likewise, that the openings in thebraid make a material which, when so worked in the Suspenders, allows the free circulation of the air, and therefore a freer escape of the perspiration of the body.

rlhe invention is exhibited in the accompanying drawings, in which-Figure l is aview illustrating the completed fabric, and Fig. 2 shows the same upon a very muchV enlarged scale.

In these views, A represents the longitudinal elastic warp-thread, and B the binding material. As shown, the elastic warp-threads are employed in groups of two, (they may bc more,) the binding material B being so interlocked therewith as to confine the groups of elastic threads together, while it at the same time separates each group from the other, so that an appearance of openness is imparted to the nishedfabric.

The binding material (see moreparticularly Fig. 2) consists of three series of threads, a b-c, (it may consist of more 4or less,) which become plaited or interlocked together between the groups of elastic warpthreads, as at d, thus separating the groups of warpthreads and forming the 4open spaces c therebetween. Thus the first series of threads a, starting, for instance, from the point x, pass over and around the outside elastic warpthread, under and between it and its companion thread, over the latter until it is met bythe second series of threads b, which become braided or interlocked therewith, as at d, and the series a pass thence underthe first elastic Warp-thread of the middle group, between it and over its companion thread until it meets the third series of threads c, where, becoming braided or interlockcd with such thread, it passes to the under side of the inner elastic warp-thread of the right-hand outside group, thence between it and its companion, and over and around the latter. llhe other series of threads, b c, in like manner pass around and between the groups of elastic warp-threads, and only meet another of the series at the points d. By thus plaiting or interlocking the IOO series of biiuling-threads between the groups of warp-threads the latter are separated a distance apart while the groups are confined together, presenting the openings @between each of the groups of warp-threads. It will be also observed that the plaited or interlocked portions d, occurring between the groups of warpthreads, prevent theui from becoming closed together when the fabric is stretched, and thus the fabric will not materially decrease in width when so stretched.

\Vhile I have described the elastic warp threads as being arranged in pairs, it is apparent that the number of threads separated by the plaited orinterlocked portions d of the binding material may be raised, as desired.

It is obvious that other material besides india-rubber might be employed for the longitudinal eordseas, for instance, a tine spiral, preferably formed of brass wire, might be so substituted. I prefer, however, the indiarubber cords. Of course in either ease these elastic threads are to be covered with a suitable material-as, for instance, cotton or silk-- before they are made up into the braid.

Though I prefer to make the fabric, as shown, with. longitudinally-extensible rubber cords, yet I may, in addition to such rubber cords, make the binding material likewise, in whole or in part, elastic.

Vhat I claim as my invention, and desire to secure by YLetters Patent, is-

1l.. An elastic fabric composed of braiding or binding threads and longitudinal or warp threads wherein the warpthreads are separated by plaited or interloeked portions of the fabric, providing perforations, substantially as described.

2. Anelastic fabrieconiposed of braiding or binding threads and longitudinal or warp threads wherein the warp-threads are composed of groups of threads, and the binding material composed of threads which become interlocked only between the groups of warpthreads, thereby providing perfor-ations, snbstantially as described.

3. An elastic fabric composed of braidiugor binding threads and longitudinal o1' warp threads wherein the warp-threads are coinposed of groups of threads, and the binding 5o material composed of threads which pass diagonally from side to side across the fabric, passing between each of the warp-threads of the groups, and becoming interlocked only between the groups of warpethreads, providing holes or pert'orations, substantially as dcscribcd.

In testimony whereof l have signed my naine to this specification in the presence of two subscribing witnesses.
